Crimson Blufffs

July 24, 1895 (Lewis Journal) "Set out at sunrise; the current very strong; passed a remarkable bluff of a crimson colored earth on Starboard intermixed with Stratas of black and brick red slate."

July 24th (Sgt. Gass) "This morning was fine, and we early prosecuted our voyage; passed a bank of very red earth..."

July 24th, 1805 (Clark Journal) "...fine day wind from the NW. I proceeded on up a creek on the derection of the Indian road at 10 oClock discovered a horse 6 miles to my left towards the river as I approached the horse found him fat and verry wild we could not get near him, we changed our Derection to the river for water having previously Crossed 5 handsom Streams in One Valley."

Yorks Islands

Wednesday July 24, 1805 (Lewis) "we saw many beaver and some otter today: the former dam up the small channels of the river between the islands and compell the river in these parts to make other channels, which as soon as it has effected that which was stoped by the beaver becomes dry and is filled up with mud sand grave and driftwood, the beaver is then compelled to seek another spot for his habitation wher(e) he again erects his dam. thus the river in many places among the clusters of islands is constantly changing the direction of such sluices as the beaver are capable of stoping or of 20 yds in with. this anamal is that way I believe to be very instrumental in adding to the number of islands with which we find the river crouded." (Sometime later, Clark penned on his map:)

Yorks 8 Islands

July 25. 1805 (Lewis) "... the valley appeared to termineate and the river was again hemmed in on both sides with high cagily and rocky cliffs, soon after entering these low mountains we passed a number of fine bold springs which burst out underneath the Land, clifts near the edge of the water; they wer very cold and freestone water."

Three Forks - the Headwaters of the Missouri River

Welcome to Three Forks and surrounding communities where the Jefferson, Madison, and Gallatin rivers converge to form the headwaters of the 2,54-mile monumental Missouri River. Native peoples prospered here over 10,000 years ago by hunting wildlife such as buffalo, elk and antelope and by crafting stone tools and weapons. Today, abundant natural resources - rich soil, minerals, and timber combine to define the prosperity of this portion of the Upper Missouri River Valley.

Independent, enterprising and hard-working people living off the land wisely developed, used and managed the natural resources for their livelihood.

Take a look around and you will discover that agriculture - wheat and various grains, cattle, and other agricultural products form the economic base of the valley. Products produced in this region are distributed worldwide! Gold, talc, and timber, along with the production of cement, add to the economic base.

The Missouri River - Source of Life

No doubt about it, the Missouri River is the lifeblood of this valley. Along this proton of the Missouri River country, notice the lush fields of grain; cattle lazily grazing; past and present mining operations; wildlife galore; forests and unlimited recreational activities.

The mighty Missouri starts its long 2,547-mile journey eastward to St. Louis at the headwaters near Three Forks where the Jefferson, Madison and Gallatin rives converge. It is one of the longest rivers in the United States, second only to the Mississippi.

The Valley Changes Forever In 1896 the Helena Water and Electric Power Company started construction of a wood and earth dam, and power plant just above the site of Canyon Ferry. That dam created Lake Sewell which was 7 miles long and 2 to 3 miles wide. Electrical power fro the plant was supplied to the smelter in East Helena. The Montana Water Board, Montana Power Company and the Bureau of Reclamation initiated a study of the water resources in 1941, which led to the construction of the new Canyon Ferry Dam which was completed in 1954. The dam and the 25-mile long Canyon Ferry Reservoir added 155,000 new acres of irrigated land and helped water an additional 82,000 acres of inadequately irrigated land. With the new reservoir came other benefits such as boating, fishing, camping as well as abundant wildlife.

Historic Travel Corridor

Whether trudging along 10,000 years ago or passing by today, travelers found this portion of the Upper Missouri Valley a well traveled corridor. Lewis and Clark pushed, paddled and pulled up the Missouri in 1805, with fur trappers following in their footsteps. Miners, farmers and homesteaders came next.

This portion of the Upper Missouri was too shallow for big steamboats. Near present-day Townsend, three small steamships were launched, but they never returned. Over 25 ferryboats crossed this 100-mile stretch of the Upper Missouri. Ferries provided an important link to the wagon road system in the late 1800s which supplied the booming mining towns.

Today, this area is a modern travel corridor that whisks travelers between Glacier and Yellowstone National Parks. The river valley still plays an integral role in the lives of people by providing water, recreation, wildlife and relaxation from the slow meandering water flowing through the valley.

Conservation and Stewardship

This portion of the Upper Missouri River Valley is still a pristine natural area of Montana where people continue to use, develop and carefully manage natural resources. Good stewardship is the key factor for long-term conservation. Mining land is being carefully reclaimed; the timber industry practices environmentally sound logging practicers; and farmers and ranchers continue to care for their land so future generations can enjoy and prosper in the valley.

Please tread lightly on the land.
